Effects of poultry raw material variation and choice of protease on protein hydrolysate quality
Lindberg, Diana; Kristoffersen, Kenneth Aase; de Vogel-van den Bosch, Heleen; Wubshet, Sileshi Gizachew; Böcker, Ulrike; Rieder, Anne; Fricke, Enno; Afseth, Nils Kristian (Peer reviewed; Journal article, 2021)The aim of this study was to investigate the role of compositional variations in side-streams from the chicken and turkey industry on product characteristics after enzymatic protein hydrolysis (EPH). Variation was obtained ... -
Encoder–decoder neural networks for predicting future FTIR spectra – application to enzymatic protein hydrolysis
Kuchta, Miroslav; Wubshet, Sileshi Gizachew; Afseth, Nils Kristian; Mardal, Kent-Andre; Liland, Kristian Hovde (Peer reviewed; Journal article, 2022)In the process of converting food-processing by-products to value-addedingredients, fine grained control of the rawmaterials, enzymes and process conditionsensures the best possible yield and eco-nomic return. However, ... -
Fourier-transform infrared spectroscopy for characterization of liquid protein solutions: A comparison of two sampling techniques
Kafle, Bijay; Böcker, Ulrike; Wubshet, Sileshi Gizachew; Dankel, Elin Katinka; Måge, Ingrid; O'Farrell, Marion; Afseth, Nils Kristian (Peer reviewed; Journal article, 2023) -
Fourier-transform infrared spectroscopy for monitoring proteolytic reactions using dry-films treated with trifluoroacetic acid
Kristoffersen, Kenneth Aase; van Amerongen, Aart; Böcker, Ulrike; Lindberg, Diana; Wubshet, Sileshi Gizachew; de Vogel-van den Bosch, Heleen; Horn, Svein Jarle; Afseth, Nils Kristian (Peer reviewed; Journal article, 2020)In this study we explore the potential of using Fourier-transform infrared (FTIR) spectra of trifluoroacetate-protein and peptide complexes for monitoring proteolytic reactions. The idea of treating dry-films of protein ... -
FTIR-based prediction of collagen content in hydrolyzed protein samples
Kristoffersen, Kenneth Aase; Måge, Ingrid; Wubshet, Sileshi Gizachew; Böcker, Ulrike; Riiser Dankel, Katinka; Lislelid, Andreas; Rønningen, Mats Aksnes; Afseth, Nils Kristian (Peer reviewed; Journal article, 2023) -
Investigating the proliferative effects of seven vegetable-derived protein hydrolysates on bovine skeletal muscle cells
Lundberg, Oscar Sebastian Arthur (Master thesis, 2022)The cultured meat industry is rapidly growing and secured 1.38 billion$ in investments for 2021. Up to 95% of the total production cost is tied to the use of fetal bovine serum. Therefore, the most pressing issue for the ... -
The role of biospectroscopy and chemometrics as enabling technologies for upcycling of raw materials from the food industry
Måge, Ingrid; Wubshet, Sileshi Gizachew; Wold, Jens Petter; Solberg, Lars Erik; Böcker, Ulrike; Dankel, Elin Katinka; Lintvedt, Tiril Aurora; Kafle, Bijay; Cattaldo, Marco; Matić, Josipa; Sorokina, Liudmila; Afseth, Nils Kristian (Peer reviewed; Journal article, 2023)It is important to utilize the entire animal in meat and fish production to ensure sustainability. Rest raw materials, such as bones, heads, trimmings, and skin, contain essential nutrients that can be transformed into ...
